Design
The Cabinet is a horizontally placed teams tires were installed on the switch-disconnector-fuses ("feeders") with a vertical arrangement of phases single connection. Each feeder performs the functions of the disconnector and protection against overloads and short circuits connected to the bottom of the cable line. For nutrition and consumer protection with rated current over 630A use a combination cabinets - module protection of outgoing line circuit breaker.
Schema auxiliary connections include:
a) measurement of the line voltage between all phases. The control bus bar voltage 0.4 kV by using a voltmeter. Voltmeter connected to the phases through the switch;
b) calculation of electrical energy to the input voltage . The metering electricity is by meter;
C) heating electricity meters. To ensure normal meter operation in winter conditions heated the heaters;
g) automatically enabling and disabling of the heating compartment Low voltage switchgear. Turning on the heaters automatically heat the temperature sensor relay;
d) lighting compartments complete transformer substation kiosk type: working - on voltage 36 In . Lighting lamp included manually household switches;
Protection against short circuits lighting circuits is the fuse from the power input and fuse with side 36 C.
e) street lighting, which turns on and off by the signal built-in photocell. T./F. 4922-305368 ;8-903-6471471
